aclnnns. (c1. 274-) This invention relates to improvements in automatic phonographrand more particularly to automatic :phonographs wherein there is a record magazine adapted to contain a plurality of records which may be played one by one in the order in which they are disposed in the record magazine, or wherein they may be played selectively as determined by the person operating the device.

The main objects of the invention are to provide an automatic phonograph which will be adapted to loperate and to reproduce records one by one in the order in which they are disposed in the record magazine, Without attention from an operator except for the matter of initiating operation of the machine by turning on power for operating the same, or by the deposition of coins for that purpose if the machine is coin controlled; to provide improved mechanism for permitting selective reproduction of the records;

to provide selecting means which may be manipulated While the apparatus is in operation; to provide selecting mechanismy whereby a plurality of records may be pre-selected in advance either while the machine is'operating or while shown is generally of the type shown in Patents No. 2,086,095 and No. 2,161,483.

The apparatus herein shown is driven by an electric motor I0, the driven shaft II of which is extended upwardly and has secured to its upper end a turn table' I2. When the apparatus is set in operation, the motor, its shaftA II and theturn table I2 are continuously rotated including the time during which records are being transferred. from the record magazine to the turn table and back again. The motor, shaft and turn tableare suitably supported and journalled in framework of the apparatus which-is .inits entirety designated I3.

A record `magazine designated I4 in its entirety includes a series of vertically spaced, horizontally disposed shelves I5 which are carried by a suitable supporting frame structure I6, the

latter being vertically slidably mounted on guide rods I "I which in turn are supported by the main frame I3.

'Ihe record magazine I4 has depending from it a rack bar I8 which meshes 'with a gear I9,

it is inoperative, or both; .to provide mechanism which is relatively simple but durable and ecient; and in general, it is the object of the inp venton to provide an improved automatic phonograph of the character indicated.

Other objects and advantages of the invention will be understood by reference to the following specication and accompanying. drawings (5 sheets) wherein there is disclosed an automatic phonograph apparatus embodying a selected form of the invention.

In the drawings: y Fig. 1 isa longitudinal vertical section; Fig. 2 is a plan section on the li'ne 2-'2 of Fig. 4 is a perspective illustrating a detail of construction which is also shown in Fig. 3;

Fig. 5 is a fragmentary side elevation of theimproved selecting mechanism, portions there--l the. latter being rotatably mounted on a shaft 20. The shaft 20 is suitably journalled inbearings carried by the frame I3 and it has secured to it a ratchet Wheel 2I which is adapted to be driven in one direction by a suitable pawl mechanism which will presentlybe described.

The weight of the magazine I4 is counterbalanced by means of a helical coil spring ,22 which has one end adjustably anchored to a pait of the main frame I3 as best shown in Figure 1, the other end of theA spring being connected as indicated at 23 by means of a exible wire or cord .24 to the periphery of a pulley 25. The

said'pulley 25 is secured ineccentric relation to p another and larger pulley 26, the two pulleys suitably journalled in portions of Vthe frame structure I3. 'Ihe large pulley 26 has a ilexible Wire or cord 28 connected to it as indicated at of being broken away or omitted 'to more clearly illustrate other portions of the mechanism; Fig. 6 is a plan section corresponding toA a portion of Fig, 2 but showing the parts in achanged position; and

Fig. 'I is a perspective illustrating the principal elements of the apparatus.

The automatic phonograph apparatus herein 29, the other end of such cord beingv connected as indicated at 30 to the lower end of the rack bar I8.

It will be seen that the contractile forceof the spring 22 will be transmitted through the pulley 25 to the pulley 26`and through the cord 28 to the magazine rack bar I8 so as to tend to lift the rack'bar and thereby elevate the magazine. The spring 22 is of such strength that it at no` time is suicient to elevate the magazine when'loaded with records, but serves I to merely counter-balance the sameso that but little extra force is required to elevate the magazine. weight of the magazine and the force of the spring is such that` the magazine will descend incident to its own weight, stretching the springv incident thereto, unless such descent is prevented by other means.

The eccentric relation Yof the pulley 25 t the pulley 26 is such that when the spring 22 is stretched and thereby has its contractile force increased, it transmits its force througha short lever arm length portion oi' the eccentric pulley 25 to the pulley 26, and by the same token, when the contractile force of the spring is reduced, it transmits such force through a longer lever arm length of the pulley 25; so that there is a substantial equalizing of the counterbalancing effect of the spring 22 regardless 4oi' the extent to which it is stretched. This arrangement aids in the production of an easily and smoothly operating mechanism.

Downward movement; of theV magazine under its own weight is normally prevented by either or both of a pair of pawls |60 and I6| A(see Figuresv 1 and 7) which servethis function in addition to a main purpose which will presently be described. 'I'he ratchet wheel 2| is in turn connected to the gear I9 through the agency of a dog 35 `pivoted intermediate its ends as shown at 36 to the ratchet wheel 2|.

The inner end of the dog is arranged to abut a pin 31 which extends from thev face of the gear I9 which is adjacent the ratchet wheel 2| and the -other end of the dog 35 is adapted to engage a stop pin 38 which serves to position the dog as shown in Figure l. A spring 39 is provided for normally holding the dog in engagement with the stop pin 38 while permitting the dog to be displaced therefrom as will presently appear. It will be seen that any tendency of the magazine I4 to move downwardly is transmitted from its rack bar I8 to the gear I9 and from the gear I9 through its pin 31 and the dog 35 to the ratchet wheel 2|, -the latter being held against rotation by the pawls |60 and I6I.

From the position of the mechanism shown Ain Figure 1, the mechanism is next operated to transfer a record from the magazine I4 to the turn table I2. This operation'is effected by means of a, cam 48 which is formed as a The relationship existing between theend pivotally mounted as indicated at 53 in conveniently accessible portions of the frame I3.

The upper end of the arm 52 is provided with a laterally extending finger 54 which is adapted, when the arm 52 is rocked to the left (in Figure 1) to engage the adjacent edge portion of a record in the magazine and move such laterally suiiiciently to-ca it to enter between Aa pair of feeding ro s 55 and 56 which are vcapable of propelling the record from the magazine I4 to the turn table I2.

When the record feeding arm 52 is moved to the left as above mentioned, the arm 49 is also moved to the left so as to cause its laterally extending upper end portion 51 to be moved from its illustrated position overlying a portion of the turn table I2, thereby to clear the turn' table for the reception of the record being delivered thereto by the feed rollers 55, 56. A suitable spring 58 stretched between a portion of the rod 41 and a transversely extending portion of a member 9| (see Fig. 2) serves to cause the roller 46 to operatively engage the cam 40.

The driven roller 56 is driven by -means of a suitable connection, including a chain 59, to a disc 60 which is adapted to be rotated alternately in opposite directions by engagement with the under side of the turn table disc I2 and the top surface of a disc 6I which is secured to the motor driven shaft II. The disc 63 is rotatably carried by an arm 62 which is pivotally mounted as indicated at 63 so as to permit the vdisc 68 to be moved vertically between the turn table I2 and disc 6|.

part of a wheel or disc 4I having thereon a'- plurality of cams and which wheel is carried by..

a shaft 42 suitably journalled for rotation in fixed posts or the like carried by the frame I3.

The shaft 42 and its cams are rotatably driven from the motor driven shaft II through the agency of a worm gear 43 on the shaft II and a worm wheel 44 on the shaft 42. The worm gear 43 is freely rotatable on the shaft II and it is adapted to be clutched to the shaft through the agency of a clutch member 45 which is vertically slidably keyed to the shaft II. Any suitable form of disengageable interconnection may be provided between the adjacent ends of the `worm gear 43 and clutch sleeve 45. :The means for controlling the clutch sleeve 45 will presentlyv be described.

The cam 4I) engages a roller 46 which is carried by a rod or strap 41, the latter being pivotally connected at one end as indicated at- 48 to an arm 49 which at its lowerend is piv- 'I'he position of the disc 66 iscontrolled by the bar 41 which has an upstanding post part 63 provided with a pin 64 which is adapted to engage eitherof a pair of spring fingers 65 and 66 which depend from said arm 62. When the bar 41 is moved to the left by the cam 40, the pin 64 will engage the spring 'nger 66 and rock the arm 62 and its disc 60 upwardly and will serve to yieldingly hold vthe disc 6II in frictional driving engagement with the lower surface of the turn table I2.

When the disc 60 is driven by engagement with the turn table I2 it will be rotated in a counterwill transmit `similar rotation to the lower feedotally mounted as indicated at in a frame portion provided for that purpose. The other end of the rod 41 is pivotallyponnected as indicated at 5I to an arm 52'f'wh`ich has its lower.

ing roll 56, whereby the latter, in cooperation with the roller-55, is capable of feeding the record as above explained.

When delivery of the record to the turn table has been completed, a centering pin 61 is automatically lowered through the usual central hole -in the record and into a suitable hole in the turn table I2. The centering pin 61 is carried by an arm 68 which is rigidly secured to the upper end of va vertically slidably mounted rod 69, the same being slidably supported by frame portions provided for that purpose.

The weight of thesarm 68 and rod 69 normally tends to cause itvto move downwardly and such movement is controlled by a cam10 vformed on said cam disc 4I. The cam 10 engages a, cam following rcller or stud 1I carried by a rock'arm 12 which is pivotally mounted intermediate its ends as indicated at 13 on a suitable ear or lug Y as indicated at 8l.

ormed as a part of the frame I8, the other end f the rock arm 12 being adapted to engage a in 1'4 which projects from the vertically slid- .bly mounted rod 69. The cam is so timed.

hat when the record has been delivered to the .urn table, the rock arm 62 will be permitted to :ook counter-clockwise (in Figure l), thereby permitting downward movement of the rod 69, arms 68 and centering pin 61. A suitable helical coil spring 15 extending between a portion oi the rock arm 12 and the rod 69 is provided for normally maintaining the cam follower 1| of the rock arm in engagement with the cam 10. Said spring also asserts a downward force on the rod 69, the arm 68 and the centering pin 61.

When a record has been delivered to the turn table and locked in operative position thereon by the centering pin 61, rotation of the cam shaft 42 is stopped by eiecting disengagement of the clutch sleeve 45 from the worm gear 43. The clutch sleeve 45 is controlled by a lever 16 which has a forked end 11 engaging in an annular recess in the clutch sleeve and the other end of said lever 16 is pivotally connected" as indicated at 18 to the vertically movable rod 69.

The lever 16 is adapted to engage a shoulder 19 formed in an upwardly extending lever 89, the latter being pivotally mounted near its lower end A spring 82 connected between the lower end of the lever 80 and a conveniently located portion of the frame structure I3 serves to normally rock the lever 89 in such a direction that the shoulder 19 thereof will overlie the lever 16.

` The rocking movement of the member 80 under the inuence of the spring 82 is limited by engagement of the` upper end portion of the member 80 with a pin 83 carried by a member 84 which is pivotally mounted on a frame part I3 and held against rotation in one direction by means of a stop pin 85. By this means frictional 68 tomove the rod 41 to the right (in Figure 1) with the-result that the record shifting arm 49 engages the edge of the record on the turn table and moves it laterally into engagement with the feeding rolls '55 and 56 `which are then operative to feed the record back into the place in the magazine from which the record was originally discharged. Y

Byexamination of Figure; of the drawings it will be seen that incident to movement of the member 41 towardthe right, the pin 64 will engage the spring nnger and move the wheel 69 downwardly into driving engagement with the disc 6| to thereby rotate the feeding rollers 55 and 56 in the proper direction for transferring the record from the turn tableto the magazine.

It may be observed that during the playing of a f As soon as the record is restored to the magazine a cam 81 engages a roller' 88 carried by any arm 89 to'rock said arm in a clockwise direction (Figure l) about the pivotal mounting 90 of said arm. The arm 89 has a link 9| pivotally connected to it, as indicated at 92, the other end of" said link 9| being pivotally connected as indicated at 93 to anarm 94 which 'is pivotally mounted at jits lower end as shown at 95 ona frame portion I3. The arm 94 is extended upwardly above the link 9| and is provided with a dog 96 which is adapted to .engage with the teeth of a rack or comb-like member 91 which. is-A carried by the depending post of 'the record magazine.

contact between the vertical edge of the member 80 and adjacent vertical face of the lever 16 is avoided so as to insure freedom of movement of the lever 16 relative to the member 88. When the rod 69 is moved downwardly, the lever 16 is also .moved downwardly and comes into engagement with the shoulder 19 which thereupon acts as a fulcrum so as to cause the clutch sleeve engaging end of the lever 16 to rock upwardly...

Such upward rocking 'movement of the clutch4 engaging end of the level` 16 serves to disengage 'said clutch member 45 from the worm gear 43, f

whereupon rotation of the cam shaft 42 ceases.

Incident to the lowering of the centering pin 61, a pick-up member 86 is lowered into operative engagement with the record then on the turn table. The pick-up member 86 is carried by an arm which is mounted so as to be both vertically and horizontally movable. up member 86 also has connected with it mechanism such as illustrated herein and which is fully illustrated and described in the aforesaid Patents No. 2,087,095 and No. 2,161,483 for rocking The pick- As shown in Figure 1, the dog 96 is out of engagement with the member 91, so`that the magazine is unlocked or free to move vertically.

During the time that a, record is being transferred between the magazine and turn table and during the time that a record is being reproduced, the dog 96 is in locking engagement with said inember 91 so as to prevent movement of the magazine` and to thereby retain the magazine in position for receiving the record in its original location upon completion of the reproduction thereof.

The cam 81 is so formed that during the reproduction of a recordv and during the shifting of a record, said dog 96 is7 permitted to engage the membergfi'.

The link 9| is extended beyond the arm. 94 and has a pawl member '98 pivoted to its outer end as indicated at 99. 'I'he other end of the pawl 98 is provided with an ear or dog |00 which is adapted to engage the teeth of the ratchet .member 2|, a suitable spring I 0I being provided between the pawl 98 and the upper end portion of the member 94 for yieldingly holding the pawl in operative engagement with said ratchet wheel. When the link 9| moves to the right, the pawl 98 i's correspondingly moved to the right and thereby rotates the ratchet wheel 2| to a predetermined extent (as determined by the travel of the link 9|).

' Therotation of the ratchet wheel 2| is trans- -mitted through the previously described dog 35 as it has been raised .a distance corresponding to the vertical spacing of the records in the magacessive repetitions of the operations thus far described.

When the iowermost record in the magazine has been reproduced and returned to the magazine, the dog 35 carried by the ratchet wheel 2| will reach a position wherein its outer end will come Vinto engagement with a lug |02 formed as a part of the frame |3 and will be thereby rocked on its pivot 39 so as to clear the pin 31 of the gear I9, thereby permitting the gear I9 to rotate on the shaft independently of. the ratchet wheel 2|. The weight of the loaded magazine I4 will then cause the magazine to move downwardly by gravity, the rack bar I9 in turn causing the gear wheel I9 to rotate ina rearward or clockwise direction (Figure l). Downward movement of the magazine is limited by engagement of the lower ends |03 (Figure 3) of the magazine structure with cushioning springs |04 carried by the guide rods I1.

So far as concerns the reproduction of the records successively in the order in which they are positioned in the magazine, the apparatus is then ready to effect transfer of the top record in the' magazine to the turn table. However, because oi' selecting mechanism presently to be described, the arrangement is such that the ratchet wheel 2| is fed a number of steps beforeA pin 31. It will its dog 35 is re-engaged with the be understood that incident to `full downward movement of the magazine, the gear I9 is rotated somewhat less thanone complete revolution, so that its pin 31 does not return to the position it occupied when the magazine was in its highest position. Hence, a certain amount of rotation of the ratchet wheel 2| independently of the gear I9 is permitted.

The apparatus herein disclosed comprises mechanism whereby a selection may be made of certain of the records in the magazine. The

`arrangement is such that any number of the records may be selected, omitting all others. If the magazine holds twenty-four records, there are providedv twenty-four keysA respectively corresponding to each record holding pocket ofthe magazine. Any of the keys may be depressed to select the corresponding records which will then be played in the order in which they appear in the magazine.

For example, if the ,records are indicated by numerals l to 24, inclusive, and it is desired to reproduce records numbered 3, 9 and 18, these' records will be reproduced successively in the order of their numbers if the selection is made when the magazine is disposed in a position Awith either of records numbered 1, 2 or 3 in alignment with the turn table. However, ii.' at the time of selection, the magazine is in such position that record numbered 7 is on the-turn table or in the magazine in alignment, with the turn table, the selected records would be played` in the order 9, 18, 3. This follows from the -above described arrangement whereby the magazine is moved conis pivoted on a shaft or rod |03 which is carried by a bracket-like member |01. The bracket member 01 is in turn secured to suitable lugs or ears |08 formed as a part of or attachedto the frame structure I3.

Each bell crank |05 includes a depending arm |09 which is movable in a slot such as I0 formed in a laterally extending ilange I|| on the lower end of the bracket plate |01. The depending arm |00 is thereby rmly supported against lateral displacement from its proper operative position. The horizontally extending or top arm 2 of each bell crank has an extension ||3 beyond the pivot |06, said extension being provided with a rounded end portion III adapted to cooperate with a helical spring ||5 which is carried by a. channel shaped bracket IIS.

The channel shaped bracket ||6 is suitably mounted on parts of the frame I3 or brackets carried thereby, and the spring ||5 is held in spaced relation to the bottom of the channel by means such as ears ||1 pressed forwardly from said bottom. The ends of the spring are anchored to the supporting channel in any suitable manner such as indicated at I8 in Figure 5.

The V rounded end portions ||4 of the bell cranks |05 normally extend beyond the front or adjacent surface of the coll spring II5. Asy indicated in Figure 3, the spring overlies the end portion ||4 and thereby serves to yieldably retain the bell crank member |05 in the position illustrated in full lines. By pressing downwardly on the key,

the bell crank arm |05 may be rocked to the position illustrated in dotted lines in Figure 3', the spring I5 yielding and permitting the said rounded end portion III tomove` upwardly past the spring, whereupon the spring restores itself `to a position` underlying said end portion as is also indicated in Figure 3. The spring is theneffective to retain the key in its depressed position until some other force restores it. It will be apparent that only a light force is required to adjust the key either up or down, the force required being somewhat dependent v'upon the strength of the helical spring l5.

To more adequately support the spring H5 against vertical displacement incident to the movement of the key, the channel I0 extends well over the top and bottom of the coil spring but it is notched out as indicated at ||9 to permit said rounded end ||4 to pass through the channeln as will be apparent from a'n inspection of Figure 3. A stop. bar |20, carried by the frame or bracket part on which the bracket plate |01 is mounted, serves to limit the upward swinging movement of the key and thereby to position all of the keys in horizontal alignment. Downward movement 9i' the keys is limited by engagement of a shouldered portion |2| of each key with the 'face oi' the bracket plate |01 as is indicated in Figure 3.

tinuously in one direction for successi ely repro- Each key is carried by a bell crank arm |05 which Each bell crank arm |09 extends downwardly below the laterally extending ange and is provided with a laterally extending lip or ear |22 for a purpose which -will presently appear.

The depending arms |09`of the bell cranks |05 are each adaptedto actuate a bar |23 which is carried by a pair of parallel links |24, the latter being pivotally connected at their outer ends to said bar |23 and pivotally mounted at their inner ends as indicated at |25 on portions of the frame I3 or suitable brackets secured thereto. One end of an arm ...|26 is pivotally connected to the bar |23, the arm extending inwardly in engagement |3 (see Figs. 2 and '1) A spring |21 connected between the arm |26 v and the frame part |3 serves to normally maintain said arm against the frame part and to maintain the arm and bar |23 in outwardly dis- .posed position as illustrated in Figures 2 and 3.

The inner end of the arm |26 is bevelled as indicated at |29 and provided with a notch or recess |30 for cooperating with a pin |3| which extends upwardly from a member |32.

The member |32 is of generally H-shape, having depending legs |33 which are pivotally connected at their lower ends to suitable ears or lugs formed integrally with the frame structure'l3 (see Figure 3). vOne upwardly extending arm |34 of said H-shaped member is connected by means of an adjustable link I 35 to a cam member |36 which is pivotally mounted at its lower end as indicated at |31 on a frame part provided for that purpose. The ca member |36 is provided at its upper end with a cam formation |38 which engages an ear |39'provided on the clutch controlling lever 16. A spring |40 stretched between a conveniently located frame part and said cam plate member |36 serves'to normally urge the cam plate to rock in a clockwise direction (Figure 7) to thereby move the clutch sleeve 45 upwardly into driving engagement with the hub of l a disc |4| which is suitably rotatably mounted on the shaft and maintained in predetermined y vertical position on said shaft. s

It will be seen that the-spring |40 transmitsA its force through the cam plate |36 and the link |35 to the H-shaped member |32, so that the latter with its upstanding pin |3| is normally urged to rock in a clockwise direction as viewed in Figures l and 1.

Clockwise rocking movement of the member |32 is prevented during the time that a record is being reproduced by engagementV of a pin |42 which projects from a part of the H-shaped member- |32, with a pin |43 which projects from the bar 9|.- The bar 9| is the one which actuates the magazine lifting pawl 98 and it will be'apparent that the spring |40 is not of sucient strength to overcome the weight of the record y magazine and records therein, as would be necessary to effect rocking movement of the member |32..

In the Qposition of the apparatus shown in the drawings, the rod 9| is moved to substantially its extreme right-hand position in which the record l' engaging arms 49 and 52 are rocked to their respective extreme right-hand positions. Hence, .in these views the -pins |42 and |43 appear in spaced relation. However, it will be understood that when the mechanism is in record reproducing position the bar 9|. is adjusted to the left so that its pin |43 ,'does engage the pin |42.

When a key is depressed, the bar |23 is moved inwardly, swinging on its supporting links |24, thereby moving the arm |26 inwardly so as to cause its notch or recess |30 to be aligned with the pin |3| The inward movement of the member |26 is such that the bevelled end |29 thereof slides past the pin |3| without moving the pin or even without necessarily engaging it, although said bevelled edge is located in very close proximity to the side of the pin.

When the arm |26 is moved inwardly in the manner explained, the operation of the mechanism upon completion of the reproduction of a record is as follows; The cam.shaf1;`42 and its mits the spring 56 to eiect transfer of the record from the turn table to the magazine and the cam 81 operatestas usual to effect onestep of upward movement of the magazine through the agency of the bar 9| and pawl member 98.

During the time the e er 9| is moved to the right by the cam 81, movement of the H- shaped member |32 under the influence of the spring |40 is prevented by means of a link |44 which is pivoted at one end as indicated at |45 Y to a part of the member |32, the other end of the link being provided with an opening |46 having@ shoulder |41 formed therein for engagement with a pin |48 which projects from a suitably located frame part. The .pin |48 may be provided with a head as indicated in Figure 1 for maintaining the adjacent end of the link in operative relation to thepin. Normally, the shoulder |41 engages said pin |48 which is xed and thereby constitutes a'stop serving to prevent movement of the link |44 to the right as is required incident to l the rocking movement of the member |32 under the influence of the spring |40. l

Upon completion of the said step of upward movement of the record magazine, the link |44 is moved upwardly so as to disengage the shoulder- |41 from the pin |49, thereby to permit the link |44 and the H-shaped member |32 to be rocked by the spring |40. To effect such disengagement of the shoulder |41 from the pin |48, the link isprovided with a-laterally extending arm part |49 which is adaptedto be engaged by a crank pin |50, carried by the cam disc 81 insuch a location that it will engage and lift said arm part and linkff |44 upon completion of said step of upward movement of the record magazine. I f

The key controlled member |26 having already been moved inwardly, the recess |30 therein is adapted to receive the pin\|3|, thereby permitting said rocking movement of the member |32 by the spring |40.

When the member |32 is permitted to rock in the manner explained, the cam plate member |36 is also rocked in a clockwise direction, whereby its cam edge |38 operates against the nger or lip |39 of the clutch sleeve controlling arm 'i6 to raise the clutch sleeve 45 into driving engagement with the disc |4|.` .The driving engagementbetween the clutch sleeve 4'5 and Worm gear 43 is thereby incidentally disengaged, with the result that the cam shaft 42 and cams come to rest.

The disc |4| carries acrank pinv |5| which is adapted to operate against the arms |52 and |53 of a lever |54 which is pivotally-connected to the l frame structure asdndicated at |55. The rotation of the disc |4| and its crank pin |5| will thus serve to rock the arm |54 back and forth once for each revolution of the disc |4|. The arm |54 is connected by means of 'a link |56 to one arm |51 of a bell crank, the other arm of which is indicated at |58. The bell crank comwise direction. The arm |58 has secured to it a pawl |6| which engages the teeth of the ratchet 2|.n such a manner that when the bell crank is rocked in a clockwise direction, the ratchet wheel i It will thus be seenthat the disc |4| and its crank pin |6| in cooperation with the arm |64, link |68 andthe described bell crank arms |51. |68 operate to eilect two steps of movement of the ratchet wheel 2| for each revolution oi' the l disc |4I. In this'manner a quick acting magazine elevating movement is obtained.` Suitable springs indicated at |62 are provided for nor- 1118115? urging the pawls |68 and |6| into operdisengagement of the clutch member 46 and disc,

The shaft 28 which rotates with the ratchet wheel 2| carries a sprocket member |63, the said sprocket being secured to the shaft so as to roagain advanced in a counter-clockwise direcd t on.

|12. Such rocking movement of the bell crank arms |18 and |19 is eifected by means of an upward extension of the pin ISI which projects through a slot |8| in the end portion of the bell crank arm |19. i

When the bar |12 is rocked inwardly in the manner explained, its movement is transmitted to the bell crank arms |18 and |19 which are then rocked in a counter-clockwise direction (in Figures 2 and '1) with theresult that the movement of the arm |19 is transmitted through the pin |3| to the H-shaped member |32,'so.as to restore the same to its initial position. The cam plate |36 is thereby -restored to its initial positate in unison therewith and in unison with'the ratchet wheel 2|. 'I'he sprocket |63 meshes with an endless chain |64 which is supported by suitable sprocket wheels |66 and |66, which are rotatably mounted on the frame structure I3. The

chain |64 carries a pair of brackets |61, one for each reach of the chain, such brackets being so formed as to constitute one of the links of the chain so as to be movable therewith as a part of the chain. As shown in Figure 4, each bracket |61 is in the form of an inverted U-shaped member. A lever |68 is pivotaliy mounted intermediate its ends as indicated at |69 on the top of each of said .brackets |61, a suitable spring means such as indicated at |18 being provided for yieldably maintaining the lever in predetermined position substantially as illustrated in Figure 4.

- Only the upper reach of the chain |64 is operatively related to the mechanism wherefore a pair of said bracket devices |61 are employed so as to make both halves of the chain successively operable. 'I'he bracket |61 on the upper reach of the chain carries its arm |68 horizontally with its inwardly extending end portion |1I in abutting sliding relation to a bar |12. The bar |12 is pivotaliy suspended by means of upstanding tion, thereby effecting disengagement of the clutch sleeve 46 and the disc |4I, and re-engagement of the clutch sleeve with the worm gear 48.

Upward movement of the magazine is then lterminated and the cam shaft 42 with its cams again caused to rotate. Theicam 81 thereupon permits the member 9| to be returned by the spring 68 to its normal position, thereby causing the dog 96 to lock the magazine in its adjusted position. 'I'he cam 48 also actuates the bar or link 41 to effect transfer of a record from the magazineto the turn table and the other operations of reproducing the selected record follow according to the manner already explained.

For restoring the depressed key sofas to get it out of the way of the end portion |11 of the arm |68, each bracket member |61 carries a pin |82 slidably mounted in theV opposite sides of the bracket and yieldingly heldin inwardly disposed position as illustrated in Figures 3 and 4 by a coil spring |83 which is interposed between one of the side arms oi the bracket 61 and a suitable collar carried by the pin |82.

at |86. A- spring such as indicated at |81 is proend arms |13 which are pivotaliy connected as shown at |14 in Figure 5 to suitable lugs or similar portions of the frame I3. A spring |16 is provided for yieldably maintaining the member |18 in outwardly disposed position as determined by a suitable pin |16 with which one of the arms |13 engages. l

When the outwardly extending end portion |11 of the lever |68 comes into engagement with the arm |89 of a depressed key, the lever |68 will be rocked in a clockwise direction (Figure 2) incident to the advancing movement of the chain |64, and the inner end portion |1| of said arm |68 will be swung inwardly (Figure 6.) thereby incidentally moving the bar |12 inwardly.

The bar |12 is adaptedto engage the arm |18 of a bell crank member, the other arm ofwlich is indicated at |19, and which bell crank is pivotaliy mounted as indicated at |88 on a suitable frame part. In the position ofy the mechanism shown in Figure 2, the arm I 18 is spaced from said member |12 but when the H-shaped member |82 is rocked in a clockwise direction as already described, the bell crank arms |18 and |19 .will also be rocked in a clockwise direction (in Figure 2) so asto cause the end portion of the arm I 18 to engage the adjacent face of said bar vided for yieldingly holding the bar |84 in inwardly disposed position as illustrated in Figure 3 wherein it is supported by engagement with a suitable abutment |88 which, in this instance, comprises part of the frame structure on which the bell crank arms |18 and |19 are pivoted.

A bell crank comprising arms |89 and |98, pivotally mounted as indicated at |9I on a part of the frame structure is associated with the bar |84, the arm |98 being located in the horizontal plane of said bar so as to be adapted to engage and rock the bar outwardly. The inner end of the bellcrank arm |89 is provided with a slot |92 which receives the upper end portion of a pin |93, which extends upwardly from an arm |94 which is pivotaliy mounted at its-lower end as indicated at |95 on `a suitably provided lug or ear of the frame I3. The arm |94 carries a roller |96 which is adapted to be engaged by a cam element |91 for rocking the arm |94 counterclockwise as seen in Figures 1 and '1.

The rocking movement of the arm |94 thus efl'ected is transmitted' into rocking movement of the bell crank arms |89 and |98, whereby the arm-|98 engages or forces the bar |84 tomove outwardly. Incident to the outward movement of the bar |84, it engages` the adjacent yend of the pin |82, moving said pin outwardly so that the outer end of the pin |82 will engage the ear or ange |22 of the bell crank arm `|89 to thereby return the same from its dotted line position as shown in Figure 3 to its full line position as there shown.

The cam |91 is relatively short as seen in Figure 1 and it releases the arm |94 as soon as restoration of the selector key has been completed, whereupon the spring |81 operates to return the bar |84, the bell crank arms |89 and |90 and the .arm |94 to normal, inactive position.

In the chain carried operating mechanism described, the relationship of the two actuating brackets |61, |61 is such that when the bracketon the uppermost reach of the chain |64 is in operative relation to the key K--24 at one end of the bank of keys (which key represents the record at the bottom of the magazine), the other actuating bracket |61 is located immediately below the sprocket |65 at the other end of the bank of keys. With each step of vertical. movement imparted to the magazine, the chain |64 is moved a distance which is equal to the distance between adjacent key arms |09; hence, it will be necessary to effect extra travel of the chain |64 when the magazine is shifted from its uppermost position to its lowermost position, in order to, move the bracket |61 from below the sprocket |65 to position on the uppermost reach of the chain adjacent the arm |08 ofV the first key indicated K-I. Such position of the bracket |61 relativeto the iirst key arm |09 is required when the iirst record is to be reproduced in order that for subsequent records the member |61 will be properly related to the key arms |09 which represent the respective records.

The extra movement of the chain |61 is eiected by means of a cam member |98 carried by the sprocket wheel Iss (Figures 3, and 7). said cam member |98 is adapted to engage a iinger |99 which is rigidly secured to and depends fromthe bar |23. When the cam- |98 engages said finger |99, the bar |23 is moved inwardly so that it adjusts the arm- |26 into positionwherein its recess |30 will permit the pin I3| to move into such recess, thereby permitting the l-I-shaped member |32 to move as required to effect rotation of the ratchet' wheel 2| by means of thedriven disc I4I and its crank pin |5| in the manner already explained.

For stopping the feeding operation of the disc and is moving toward said pin to re-establish its driving relation thereto. It will be remembered that incident to the lowering of the magazine, the gear wheel I9 Awas rotated in a reverse direction, the pin 31 being freed from the dog 35 and being carried bythe gear I9 through a path of travel somewhat less than 360 degrees. In this way, thepin 31 temporarily acquires a position in advance of the dog 35 and the dog is. in effect, caught up with the pin 31 -as an incident to the rotation of the ratchet 2| incident to the operation of the cam |98.

For the purpose of permitting accurate adjustment of the sprocket wheel |63 and chain |64 with the parts carried thereby relative 'to the magazine and its actuating mechanism, the sprocket |63 is preferably connected to the shaft 20 through the agency o f a'n arm 208-which is fixedly secured to said shaft and is provided with a pair of ears 208' which embrace one of the spokes of the sprocket. Adjusting lscrews 209 carried by said ears 208,.and adapted to engage the opposite edges of such spoke facilitate adjustment of the relative position of the sprocket and iI and its crank pin i5|, the sprocket |63.is provided with a crank pin 200 which is adapted to engage the e'nd portion 20| of an arm202 which is pivotally mounted as shown at 203 on a portion oi the frame I3. Said arm 202 has an edge portion or prominence 204 which is adapted to engage an adjustable abutment 205 carried by an extension arm 206 of the H-shaped member |32. Said 'crank pin 200 is so positioned on the sprocket wheel |63 that it will actuate the arm 202 vand member |32/ at the proper time to disengage the clutch sleeve from the disc |4| to stop rotation of the latter when the bracket member |61 reaches its starting position on the upper reach of the chain.

The sprocket |63 is also provided with 'a peripheral recess 201, the same being adapted to permit passage of the depending portion of the bracket |31 and its arm |68 on the lower reach of the chain. This arrangement permits passage of the member |61 without impairing driving Iengagement between the sprocket |63 and the clain |64. During the rotation of the ratchet 2| as eiected by the driving-disc 14| during the operation of the cam |98,;the pawl or dog 35 carried by the ratchet is not in engagement with the driving pin y 31 of the gear wheel |9 but instead, is free thereof arm 208.

The described mechanism may have associatedA with it coin control mechanism such as indicated generally at 2I0 in Figure 2, the same being connected to the operating, mechanism through a lever 2|| pivoted on a part of the frame I3 and provided with .an end portion 2 |2 which is adapted to be engaged by a pin 2|3 carried by the cam disc structure as shown in Figures 2 and 7.

It will be observed that the structure as described is operative', in the absence of coin con trolled mechanism, to continuously reproduce the records in the magazine successively, beginning with any of records in the magazine, then playing each of the records disposed in lower pockets until the lowermost record is reproduced, whereupon the magazine is lowered so that the top record will be reproduced followed by those disposed thereunder.

Similarly, in the pre-selection of records by means of the selector keys, the uppermost se"- lected record (either in alignment withthe turn table or in a position therebelow) will rst be reproduced and then the selectedV records below i such uppermostrecord will be reproduced successively in the order in which they appear in the'magazine. Thereafter, any records which Were'selected from`the magazine in positions above the record in playing position will be re- Cil produced successively in the order in which they appear in the magazine.

The details of the described construction may, of course, be varied considerably Without departing from the principles of-thel mechanism described, Vwherefore it should be understood that the following claims are not intended tobe restricted to the specific details of construction but are directed to the structure required for carrying out the principles of operation embodied in the described structure.
